Jesse Anderson created BEAM-645: ----------------------------------- Summary: Running Wordcount in Spark Checks Locally and Outputs in HDFS Key: BEAM-645 URL: https://issues.apache.org/jira/browse/BEAM-645 Project: Beam Issue Type: Bug Components: runner-spark Affects Versions: 0.3.0-incubating Reporter: Jesse Anderson Assignee: Amit Sela
When running the Wordcount example with the Spark runner, the Spark runner uses the input file in HDFS. When the program performs its startup checks, it looks for the file in the local filesystem. To workaround this issue, you have to create a file in the local filesystem and put the actual file in HDFS. Here is the stack trace when the file doesn't exist in the local filesystem: {quote}Exception in thread "main" java.lang.IllegalStateException: Unable to find any files matching Macbeth.txt at org.apache.beam.sdk.repackaged.com.google.common.base.Preconditions.checkState(Preconditions.java:199) at org.apache.beam.sdk.io.TextIO$Read$Bound.apply(TextIO.java:279) at org.apache.beam.sdk.io.TextIO$Read$Bound.apply(TextIO.java:192) at org.apache.beam.sdk.runners.PipelineRunner.apply(PipelineRunner.java:76) at org.apache.beam.runners.spark.SparkRunner.apply(SparkRunner.java:128) at org.apache.beam.sdk.Pipeline.applyInternal(Pipeline.java:400) at org.apache.beam.sdk.Pipeline.applyTransform(Pipeline.java:323) at org.apache.beam.sdk.values.PBegin.apply(PBegin.java:58) at org.apache.beam.sdk.Pipeline.apply(Pipeline.java:173) at org.apache.beam.examples.WordCount.main(WordCount.java:195) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.spark.deploy.SparkSubmit$.org$apache$spark$deploy$SparkSubmit$$runMain(SparkSubmit.scala:731) at org.apache.spark.deploy.SparkSubmit$.doRunMain$1(SparkSubmit.scala:181) at org.apache.spark.deploy.SparkSubmit$.submit(SparkSubmit.scala:206) at org.apache.spark.deploy.SparkSubmit$.main(SparkSubmit.scala:121) at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala) {quote} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
